DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Reference Figures 1 to 14 As shown, an intelligent box transformer provided by an embodiment of the present invention includes a box body 100, a box door 200, a filtering mechanism and an air supply mechanism. The box door 200 is vertically arranged on the box body 100, and a plurality of through-hole components are provided on the box door 200, and the plurality of through-hole components are sequentially distributed along the vertical direction, and each through-hole component includes a plurality of first filtering holes 201, and the plurality of first filtering holes 201 are sequentially distributed along the first direction, and the first direction is the horizontal direction.

[0043] A plurality of first limiting rods 210 are arranged on the inner side wall of the box door 200, and the inner side wall of the box door 200 is a side located in the box body 100. Each first limiting rod 210 is arranged along the first direction, and the plurality of first limiting rods 210 are sequentially distributed along the vertical direction. Each first limiting rod 210 is located between two adjacent through-hole components, and each first limiting rod 210 is provided with a first through slot, which is arranged along the first direction and passes through the first limiting rod 210.

[0044] The filter mechanism includes a filter plate 300 and a limit assembly. The filter plate 300 is elastic and vertically arranged. The filter plate 300 passes through a plurality of first through slots from top to bottom in sequence. A plurality of second filter holes are provided on the filter plate 300. The air supply mechanism is used to allow external gas to enter the box body 100. The filter plate 300 has a first state and a second state. The first state of the filter plate 300 is a vertical state. The second state of the filter plate 300 is that, under the action of the gas, the corresponding parts of the filter plate 300 and the first filter hole 201 bulge inward. The filter plate 300 switches from the first state to the second state under the action of the gas.

[0045] The limiting assembly is arranged on the door 200, and includes a first limiting plate 400 and a second limiting plate 500. The first limiting plate 400 is located on the upper side of the second limiting plate 500, and the first limiting plate 400 and the second limiting plate 500 are used to limit the moving direction of the filter plate 300. The limiting assembly has a third state and a fourth state. The third state of the limiting assembly is that the first limiting plate 400 and the second limiting plate 500 allow the filter plate 300 to move upward, and the fourth state of the limiting assembly is that the first limiting plate 400 and the second limiting plate 500 allow the filter plate 300 to move downward.

[0046] In the initial state, the limiting assembly is in the third state, and the first limiting plate 400 and the second limiting plate 500 allow the filter plate 300 to move upward. The filter plate 300 is in the first state, and the filter plate 300 is in a straight plate shape.

[0047] The air supply mechanism allows external air to enter the box 100, and the second filter hole on the filter plate 300 that is connected to the first filter hole 201 filters the air. Since the filter plate 300 is elastic, and another part of the filter plate 300 is in the first through groove, when the second filter hole at the corresponding position of the filter plate 300 and the first filter hole 201 is blocked, this part of the filter plate 300 will protrude into the box 100, and the filter plate 300 is in the second state. Since the filter plate 300 can only move upward, the length required when the filter plate 300 is in an arc shape is more than the length required when the filter plate 300 is in a straight plate shape, so the lower end of the filter plate 300 moves upward to supplement the length required for the arc shape of the filter plate 300. At this time, the filtering area of ​​the filter plate 300 used for filtering is increased, and the filtering efficiency is improved.

[0048] After filtering for a period of time, the filter plate 300 stops supplying air to the box 100. At this time, the filter plate 300 is reset under the action of its own elasticity, and the filter plate 300 is transformed from the second state to the first state. When the filter plate 300 is deformed, the impurities on the filter plate 300 are ejected to the first filter hole 201, thereby cleaning the filter plate 300. Due to the action of the limit assembly, the filter plate 300 can only move upward at this time. When the filter plate 300 is reset, it continues to move upward, so that the blocked second filter hole enters the first through groove, and the unblocked second filter hole is connected to the first filter hole 201. Start the air pump again, and the unblocked second filter hole is filtered at this time. Therefore, all the second filter holes on the filter plate 300 can filter, preventing a part of the filter plate 300 from being worn while another part of the filter plate 300 is not used, thereby extending the service life of the filter plate 300.

[0049] When the filter plate 300 moves upward for a certain distance, the limit assembly is adjusted to the fourth state so that the filter plate 300 can only move downward. The filter plate 300 moves up and down reciprocatingly, and the work is more continuous and the work efficiency is higher.

[0050] In this embodiment, the first limit plate 400 includes a first rotating shaft 410, a first connecting plate 420 and a second connecting plate 430, and the first rotating shaft 410, the first connecting plate 420 and the second connecting plate 430 are all arranged along the first direction. The first rotating shaft 410 is arranged on the door 200, and the first rotating shaft 410 can rotate around its own axis. The first connecting plate 420 and the second connecting plate 430 are both fixedly arranged on the first rotating shaft 410, and the first connecting plate 420 is on the upper side of the second connecting plate 430, and the angle between the first connecting plate 420 and the second connecting plate 430 is an obtuse angle.

The first one-way ratchet 421 and the second one-way ratchet 431 are in opposite directions. The first one-way ratchet 421 allows the filter plate 300 to move downward and restricts the filter plate 300 from moving upward, while the second one-way ratchet 431 allows the filter plate 300 to move upward and restricts the filter plate 300 from moving downward.

The third connecting plate 520 and the fourth connecting plate 530 are both fixedly arranged on the second rotating shaft 510, and the third connecting plate 520 is located on the upper side of the fourth connecting plate 530, and the angle between the third connecting plate 520 and the fourth connecting plate 530 is an obtuse angle. The third one-way ratchet 521 is fixedly arranged on the third connecting plate 520, and the fourth one-way ratchet 531 is fixedly arranged on the fourth connecting plate 530. The third one-way ratchet 521 and the fourth one-way ratchet 531 are both retractable, and the third one-way ratchet 521 or the fourth one-way ratchet 531 is used to abut against the side of the filter plate 300 away from the box door 200. The third one-way ratchet 521 and the fourth one-way ratchet 531 are in opposite directions. The third one-way ratchet 521 allows the filter plate 300 to move downward and restricts the filter plate 300 from moving upward. The fourth one-way ratchet 531 allows the filter plate 300 to move upward and restricts the filter plate 300 from moving downward.

[0052] When the limiting assembly is in the third state, the second one-way ratchet 431, the fourth one-way ratchet 531 and the filter plate 300 are against each other, so that the filter plate 300 can move upward. When the limiting assembly is in the fourth state, the first one-way ratchet 421, the third one-way ratchet 521 and the filter plate 300 are against each other, so that the filter plate 300 can move downward.

[0056] When the adjusting frame 540 moves, the adjusting frame 540 drives the first rotating disk to rotate through the first connecting rod 412, thereby driving the first rotating shaft 410 to rotate. The adjusting frame 540 drives the second rotating disk to rotate through the second connecting rod 512, thereby driving the second rotating shaft 510 to rotate.

[0059] When the filter plate 300 continuously moves upward and drives the second baffle 320 to move upward synchronously, after the second baffle 320 moves to abut against the second horizontal rod 542, the second baffle 320 continues to move upward, and the second baffle 320 pushes the adjustment frame 540 to move upward synchronously.

The first slider is used to be slidably disposed in the first mounting groove or the second mounting groove. A second slider is disposed in each second slide groove, a second spring is fixedly disposed on the second slider, and the second spring is fixedly connected to the inner wall of the second slide groove. The second slider is used to be slidably disposed in the third mounting groove 513 or the fourth mounting groove 514.

[0064] In this embodiment, the air supply mechanism includes an air pump, which is disposed in the box body 100 , and an air outlet is provided on the box body 100 .

[0065] In this embodiment, a water retaining plate 250 is disposed on each filter hole. The water retaining plate 250 is located on the outer wall of the box body 100 to prevent rainwater from entering the box body 100 .

[0066] In this embodiment, a distance sensor is provided in the housing 100, and the distance sensor is used to detect the distance of the filter plate 300 protruding inward. A controller is provided on the air pump, and the controller receives a signal from the distance sensor and controls the opening and closing of the air pump. When the filter plate 300 is in the first state, the controller turns on the air pump. When the distance of the filter plate 300 protruding inward detected by the distance sensor exceeds a preset distance, the controller receives a signal from the distance sensor and turns off the air pump.

[0067] Working process: In the initial state, the limit assembly is in the third state, the second one-way ratchet 431, the fourth one-way ratchet 531 and the filter plate 300 are against each other, so that the filter plate 300 can move upward. The first slider is in the second mounting groove, and the second slider is in the fourth mounting groove 514. In the initial state, the air pump is not started. At this time, the filter plate 300 is in the first state, and the filter plate 300 is in a straight plate shape. Some of the second filter holes on the filter plate 300 are connected to the first filter holes 201.

[0068] The air pump is started to suck air from the outside into the box 100 for heat dissipation. During this process, impurities in the air are intercepted by the filter plate 300 and do not enter the box 100. The second filter hole on the filter plate 300 connected to the first filter hole 201 filters the air.

[0069] Since the filter plate 300 is elastic and another part of the filter plate 300 is in the first through groove, when the second filter hole at the place where the filter plate 300 and the first filter hole 201 correspond is blocked, this part of the filter plate 300 will protrude into the box 100, and the filter plate 300 is in the second state. Since the filter plate 300 can only move upward, the length required when the filter plate 300 is in an arc shape is more than the length required when it is in a straight plate shape, so the lower end of the filter plate 300 moves upward to supplement the length required when the filter plate 300 is in an arc shape. At this time, the filtering area of ​​the filter plate 300 used for filtering is increased, and the filtering efficiency is improved.

[0070] When the distance sensor detects that the inward protrusion of the filter plate 300 exceeds the preset distance, the controller receives the signal from the distance sensor and turns off the air pump. At this time, the filter plate 300 is reset under the action of its own elasticity, and the filter plate 300 is transformed from the second state to the first state. When the filter plate 300 is deformed, the impurities on the filter plate 300 are ejected to the first filter hole 201, thereby cleaning the filter plate 300. Due to the action of the limit assembly, the filter plate 300 can only move upward at this time. When the filter plate 300 is reset, it continues to move upward, so that the blocked second filter hole enters the first through groove, and the unblocked second filter hole is connected to the first filter hole 201.

[0071] The air pump is started again, and the unblocked second filter holes are used for filtering. When the portion on the filter plate 300 bulges inward again and exceeds the preset distance, the air pump is turned off again, and the filter plate 300 is reset and moves upward again. Therefore, all the second filter holes on the filter plate 300 can be used for filtering, preventing a part of the filter plate 300 from being worn while another part is not used, thereby extending the service life of the filter plate 300.

[0072] When the filter plate 300 continuously moves upward and drives the second stop bar 320 to move upward synchronously, after the second stop bar 320 moves to abut against the second horizontal rod 542, the second stop bar 320 continues to move upward, and the second stop bar 320 pushes the adjustment frame 540 to move upward synchronously. When the adjustment frame 540 moves, the adjustment frame 540 drives the first rotating disk to rotate through the first connecting rod 412, and then drives the first rotating shaft 410 to rotate. The first slider disengages from the second mounting groove and enters the first mounting groove. At this time, the first one-way ratchet 421 contacts the filter plate 300. The adjustment frame 540 drives the second rotating disk to rotate through the second connecting rod 512, and then drives the second rotating shaft 510 to rotate. The second slider disengages from the fourth mounting groove 514 and enters the third mounting groove 513. At this time, the fourth one-way ratchet 531 contacts the filter plate 300. The limit assembly is in the fourth state at this time, and the limit assembly allows the filter plate 300 to move downward. The filter plate 300 moves up and down reciprocatingly, and the work is more continuous and the work efficiency is higher.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
